Thanks largely to the way Congressional districts were drawn in the latest round of redistricting, even a dramatic wave election like the one in 2008 that swept President Obama into power and added to Democratic majorities in Congress would do little to alter the composition of the Republican-controlled House of Representatives, a new, nonpartisan study found.

FairVote, an organization that examines voting patterns and laws, predicts that Republicans will maintain control of the House in 2014 unless Democrats meet the unlikely threshold of winning 56 percent of the vote nationwide.
